Answer:
58.32
Explanation:
The mass number is one mole and for Mg it is 24.306 for O it is 15.999 and for H it is 1.008. because O and H have 2, you multiply them by 2 and add all the numbers and it equals 58.32
Answer: It is a Lewis acid/base reaction, and 
is the Lewis acid.
Explanation:
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
can readily accept electrons and thus act as a lewis acid which is short of electrons.
can readily lose electrons and thus act as a lewis base which has excess of electrons.
It is a Lewis acid/base reaction, and is the Lewis acid.
Answer:
C. Involves a metal and a nonmetal.
Explanation:
Ionic compound involves a metal and a non-metal. Ionic compounds have electrovalent bonds between them.
These compounds are usually made up of metals and non - metals combining to form a unit.
- The metals usually has low electronegativity and transfers it electrons to the non - metal.
- The non-metal has high affinity for the electron.
- The electrostatic attraction between the ions formed results in the ionic bond.
Fire is a risk in all commercial kitchens. Open flames, grease, poor house-keeping practices, electrical hazards and flammable materials are common causes of restaurant fires.
